Environmental Consulting AEI serves a wide range of clients nationwide, providing strategies to evaluate and resolve complex environmental challenges. AEI’s environmental consulting services assist our clients in making informed business decisions by providing valuable information regarding potential environmental liabilities. Assessments are designed to meet the client’s needs, ranging from due diligence for real estate management and transactions to ensuring compliance with federal, state and local environmental regulations. Phase I Environmental Site Assessments (ESA) Phase I ESAs are an integral part of the due diligence and decision-making process for lending and property purchase decisions. A Phase I ESA includes a site visit and a historical and regulatory review that is designed to identify environmental issues such as current and historic environmental conditions that may affect property values, pose a financial liability to the purchaser or lender, or affect the ability of a borrower to repay a loan obligation. Clients may also obtain a Phase I ESA in order to satisfy requirements of the "innocent landowner defense" or other available defenses to environmental liability under CERCLA. AEI’s Phase I Environmental Site Assessment (ESA) meets the most current ASTM Standard for Phase I ESAs, and involves the following activities: • Site inspection • Adjacent/ surrounding property reconnaissance • A review of historical documentation (i.e. fire insurance maps, city directories and aerial photographs) • A review of hazardous material and petroleum product storage, spill and disposal records • Local, regional and state agency file review • Interviews with the property owner, tenants and property managers • Preparation of a report documenting the findings, conclusions and recommendations • Asbestos, lead, radon and mold evaluation (on request) AEI’s reports are designed to be clear and concise. Our Phase I Environmental Site Assessment (ESA) reports are an essential part to many commercial and industrial real estate transactions and are conducted in accordance with the most current ASTM E 1527 Standard Practice for Environmental Site Assessments. Additions to our Phase I AEI will customize your Phase I report upon request. reports can include: Some customizations include: • Wetlands review • Client-specific scopes of work • Flood Zone • Local and Government agencies / reviews • Evaluation for mold, asbestos, • Standard and Poor’s protocols lead-based paint and/or radon • Housing & Urban Development (HUD) requirements • Environmental lien search and • Small Business Administration (SBA) requirements Chain of Title review • Freddie Mac and Fannie Mae requirements
Environmental Consulting Phase II Subsurface Investigation When environmental due diligence goes beyond the scope of a Phase I Environmental Site Assessment, a Phase II Subsurface Investigation can be necessary to further evaluate the potential of contamination on your property. AEI provides Phase II Subsurface Investigations for clients nationwide. AEI’s professional geologists and engineers design customized scopes of work addressing specific property challenges. AEI’s Phase II Investigations may include: • Soil and groundwater sampling and laboratory analysis for potentially harmful chemicals • Sediment and surface water sampling and analysis • Soil vapor and indoor air sampling and laboratory analysis • Groundwater flow modeling and laboratory analysis • Drilling and sampling temporary bore holes • Installation and sampling monitoring wells • Geophysical surveys • Indoor-air vapor intrusion assessment • Vapor encroachment assessment • Contaminant source differentiation Once the field investigation has been completed, a state-certified laboratory will conduct the sample analysis. AEI will then prepare a report signed by a state-designated professional geologist or engineer that details the analytical laboratory data and field investigation conclusions along with any recommendations. Environmental Transaction Screen (ETS) AEI provides Environmental Transaction Screens (ETS) as an alternative approach to a Phase I Environmental Site Assessment. The ETS consists of a limited scope of work and is designed to assess the environmental condition of commercial real estate. An ETS is recommended for low risk property types or properties with extensive historical information available. The report issued will document potential environmental conditions on the property or on the adjacent properties. The Transaction Screen includes: • Site inspection • Owner / occupant interview and questionnaire • Limited historical search • Regulatory database review • Preparation of a report documenting the findings, conclusions and recommendations AEI’s ETS reports are compliant with the most current ASTM E1528 standard
Environmental ConsultingRecords Search with Risk Assessment (RSRA)Records Search and Risk Assessment is a limited environmental due diligencetool intended to inexpensively evaluate the likelihood of contamination on thesubject property and its adjacent properties. A RSRA is typically used for SBA financing.The assessment concludes whether the subject property is either “high risk”, "moderate risk"or “low risk” for contamination. If the property is not determined “low risk”, an additionalenvironmental investigation may be required.The RSRA assessment involves: • Database search of federal, state and local regulatory agencies • Limited historical record review of the subject property and adjacent sites • Desktop review of the above information by an Environmental ProfessionalThis report meets the RSRA scope of the Small Business Administration (SBA).Agency Environmental ReportsAEI is experienced in providing assessments that meet agency requirements, such as US Housing & UrbanDevelopment (HUD), Fannie Mae, Freddie Mac, and the US Small Business Administration. AEI demonstrates aproven track record of providing reports that meet the approval of these agencies, allowing transactions to smoothlyproceed through the agency’s review process.Compliance ServicesAEI assists both public and private clients in understanding and developing compliance management planning tomeet environmental regulations. AEI also assists with compliance management including evaluations andrecommendations for corrective action. AEI provides diverse compliance support to help keep you aware of currentregulations while helping you stay within your corporate budget.National Environmental Policy Act (NEPA)AEI performs FCC-NEPA Compliance consulting including natural/biological, and cultural resource studies in supportof the wireless industry for both new towers (FCC Form 620) and collocations (FCC Form 621).These investigations evaluate: • Designated wilderness areas • Designated wildlife preserves • Threatened or endangered species and critical habitats • Historic places and Native American religious sites • Floodplains • Wetlands and surface waterways • High intensity lights in residential neighborhoods
Environmental ConsultingStormwater ComplianceAEI reviews Notice of Intent (NOI) and Stormwater Pollution Prevention Plans(SWPPPs) and performs limited stormwater compliance inspection of properties.AEI contacts the oversight agencies to verify compliance with requirements and identifyany potential costly liabilities or outstanding violations. Inspections include a review of the following: • Presence of natural resource areas • Presence of Best Management Practices (BMPs) • Condition and location of perimeter controls and sediment barriers • Inspection of discharge points • Potential for release of contaminants to stormwaterAEI also provides estimated costs for implementation and ongoing maintenance/inspection requirements,as well as costs to stabilize the property, to comply with stormwater regulations.Consulting ReviewsWhen a client requires an expert evaluation of findings done by another environmental firm or to identifywhether the report was completed in accordance with regulatory standards, AEI conducts a consulting or “peer”review. AEI’s team of environmental professionals provides these reviews on a variety of subject matter includingdue diligence assessments, site investigation and remediation, and industrial hygiene reports.
Engineering ConsultingSince its founding in 1992, AEI Consultants has performed thousands ofengineering assessments on various commercial property types for bothprivate and public clients throughout North America.AEI is an industry leader in engineering due diligence services because of ourdemonstrated ability to work closely with our clients, understand their particular dealrequirements and apply our knowledge of the specifics of the deal, property type, andproperty location to ensure the most reliable and thorough reporting. With nearly twentyyears of industry experience, AEI has developed a keen understanding of the specific needsand requirements of each lending institution. We pride ourselves on our willingness to workhand-in-hand with our clients to tailor a deliverable that meets both lender and client specificscopes of work and report formatting.AEI’s Engineering Service Offerings include: • Debt Financing Property Condition-Physical Needs Assessments (PCA/PNA) • Seismic Risk Analysis utilizing both the SEL and SUL methodologies • Equity-Financing Property Condition Evaluations • Green Building Assessments • Building Energy Performance Assessments / Energy Star Audits • LEED ConsultingAEI provides these services for a myriad of financial institutions including domestic and foreign commercial banksand lenders, mortgage conduits, agency institutions like Freddie Mac, Fannie Mae and HUD, insurance companies,private real-estate companies, investment banks, and individual investors to ensure the underwritten value of aloan is consistent with the condition of the property at the time of inspection.Property Condition AssessmentsThe purpose of a Property Condition Assessment is to observe and report on the physical condition of the subjectproperty and to provide professional recommendations regarding future issues including financial risk or liability tothe client.Major structural, electrical, plumbing and HVAC components of each structure, as well as site improvements, arecarefully examined for condition, status of completion, general code conformance, life cycle costs, sufficiency fortheir intended use, and extent of defects and depreciation. AEI’s Building Sciences team interviews site personnel,performs document reviews and conducts walk-through surveys noting the physical condition of the buildingsystems and components.Systems surveyed will include the following: • Site and Grounds - pavement, curbs, loading docks, walks, landscaping, irrigation, site drainage, exterior lighting, walls, fencing/railings, signage and exterior amenities. • Structural Systems - Foundations and structural framing of walls, columns, intermediate floors and roofs.
Engineering ConsultingProperty Condition Assessments (continued) • Building Envelope - Roofing systems, exterior finishes, stairs and steps, exterior doors and windows. • Interior Building components - Interior finishes of common areas and tenant areas. Condition of soft goods will not be assessed. • Mechanical Systems - Property-owned electrical, heating ventilation/ air conditioning, plumbing and conveyance systems. • Safety and Code Compliance - Life safety, fire suppression systems, and general visual review of property compliance to the Americans with Disabilities Act (ADA). AEI services include contacting the local building, zoning, and fire department / authorities to identify any currently outstanding building or fire code violations at the subject property.Upon completion of the physical assessment of the property, AEI will provide a Property Condition Report(PCR) outlining the systems and components along with any deferred maintenance or deficiencies observed.Based on industry standard, AEI then formulates a list of immediate repairs and costs that will be incurred.Immediate repairs can be defined as significant building code violations, fire code violations, safety concernsand deterioration to the building caused by deferred maintenance. In addition to the assessment, AEI develops aModified Capital Reserves Schedule that approximates repairs and replacement costs most likely to occur over theevaluation period. This schedule allows the client to plan for large expenditures in advance of their replacement.AEI’s PCA reports comply with industry standards based on ASTM E-2018-08 requirements along with Freddie Mac,Fannie Mae or HUD guidelines. Customized scopes are also available.Seismic Risk AnalysisAEI provides a seismic risk analysis in a Seismic Loss (SL) report in accordance with ASTM Standards E2026-07 andE2557-07. The SL report summarizes the risk of structural failure due to the vibratory motion from the maximum probableearthquake event that has a 10-percent chance of exceedance in a 50-year exposure period, or a 475-year return period.AEI utilizes the Scenario Expected Loss Design Basis Earthquake (SELDBE) as the seismic loss damage ratio (commonlyreferred to as Probable Maximum Loss - PML). (SELDBE) is defined by ASTM E 2026-07 as the expected (mean) earthquakeloss to a building resulting from a specified seismic induced ground motion (peak ground acceleration). The specifiedpeak ground acceleration is based on the probabilistic seismic hazard analyses program FRISKSP-3.01b and the USGSdatabase.The ASTM recently released guidance, ASTM 2557-07, indicating the use of the (SELDBE) estimate for CMBStransactions.AEI can also provide the Scenario Upper Loss (SUL), which represents the scenario loss that has a 10% probability ofexceedance due to the specified ground motion of the scenario considered. Both methods take into account variousfactors including construction type, site condition, soil type and location of the building to known faults. The specificmethodologies are governed by the lender, but all include the following: • Cursory review of available geologic and soils reports and drawings. • Site visit and general assessment of the property, building(s), related facilities and general site characteristics. • Preliminary assessment of earthquake ground shaking, liquefaction and fault surface rupture potential based on historical regional hazard data. • Preparation of a report including a list of general seismic deficiencies and preliminary estimate of facility earth quake damage loss based on empirical loss estimation methodologies.The United States is divided into seismic zones depending on hazard risk. Properties in seismically active areas have ahigher risk of suffering significant damage in the event of a major earthquake. Knowing the seismic risk of yourproperty is important to avoid future expenditures.
Engineering ConsultingPhysical Needs Assessment (PNA)The Physical Needs Assessment (PNA) is designed to address all existing conditions,outstanding maintenance issues and to identify any building code violations.PNA reports can be modified according to a client’s particular inquiry. Upon completionof the physical assessment of the property, AEI’s professional staff will provide the clientany recommendations to correct any conditions that may affect the health or safety ofcurrent or future residents. AEI will then formulate and present our recommendations with abudget to enhance the physical and aesthetic condition of the property to maximize its positionin the market place. The PNA can be an essential tool in determining the subject site value andapproximate cost in possible repairs and/or investment in the property.AEI’s PNA report provides our clients with an assessment of the subject property’s overall condition.The report discusses the following components of each site:• Site and Grounds - pavement, curbs, loading docks, walks, landscaping, irrigation, site drainage, exterior lighting, walls, fencing/railings, signage and exterior amenities.• Structural Systems - Foundations and structural framing of walls, columns, intermediate floors and roofs.• Building Envelope - Roofing systems, exterior finishes, stairs and steps, exterior doors and windows.• Interior Building components (FF&E) - Interior finishes of common areas and tenant areas. Condition of soft goods will not be assessed.• Mechanical, Electrical and Plumbing (MEP) Systems - Property-owned electrical, heating ventilation/air conditioning, plumbing and conveyance systems.• Safety and Code Compliance - Life safety, fire suppression systems, and general visual review of property compliance to the Americans with Disabilities Act (ADA). AEI will also contact the local building, zoning, and fire department / authorities to identify any currently outstanding building or fire code violations at the property.These components are carefully examined for condition, remaining useful life, general code conformance, life cycle costs,sufficiency for their intended use, and extent of defects and depreciation. In addition to a written report discussing thephysical assessment of the property, AEI provides immediate/short term cost tables outlining the costs associated withcorrecting the deficiencies that require immediate attention, mainly code, life safety or ADA deficiencies. AEI alsoformulates and presents a second set of cost tables which outline the recommendations and costs associated with ongoing maintenance and upkeep over the evaluation (loan) period.
Engineering ConsultingGreen Building AssessmentsGreen building assessments help clients estimate the costs and benefits ofsustainable investments and determine where to focus these costs in providingthe greatest “green” impact.Building Energy Performance Assessments (BEPA)Based on an increased awareness about energy efficiency and “green” buildings, ASTM Internationaldeveloped the Standard Practice for Building Energy Performance Assessment (BEPA) for a BuildingInvolved in a Real Estate Transaction (ASTM E2797).The goal of the BEPA process is to document historical energy performance, identify the range of buildingenergy use and costs (upper and lower limit scenarios), and provide a pro forma energy use and pro forma energycost for the building.A BEPA Study has five components: • Site Visit - To observe the building during the walk-through and document the building characteristics (property type, building age, last major renovation, number of floors, square footage, occupancy, heating system, air conditioning system, energy sources etc.), conduct interviews and collect records not previously provided. • Interviews - With the present owner, operator, and/or key site manager at the building; • Records collection - Collect and compile the records necessary (energy consumption, energy costs, weather data, hours of operation, occupancy rates etc. over the previous three years, with a minimum of one year, or back to the last major building renovation if completed less than three years ago); • Records review and analysis - Review and analysis of records collected; • Report - Report on the findings related to building energy use and energy cost.A BEPA as described in this practice is appropriate for properties where utility/energy costs are centralized and paid by theproperty owner, manager, or operator and may include, but are not limited to, office, retail, hotel/lodging, warehouse, andindustrial properties.Information collected is standardized in performance metrics kBTU/SF and normalized as appropriate for occupancy, degree days,and other variables. A BEPA can be further expanded utilizing the Energy Star program to allow for benchmarking of the building.Green Property Condition AssessmentsAEI’s team of experienced professionals enables clients to achieve their energy efficiency goals by offering energyperformance assessments and energy saving recommendations. Awareness of energy waste will help customers improvethe energy performance of their facilities, leading to improvements to the company’s bottom line and ultimately savingsignificant amounts of energy. These services are provided independently or as a supplemental service to a PropertyCondition Assessment.Energy Audits assist clients to optimize energy performance by: • Determining how energy is being consumed • Reducing energy consumption and operating cost • Complying with new laws / regulations* • Promoting social responsibility by reducing green house gas emissions • Increasing tenant satisfaction and productivity
Engineering ConsultingGeotechnical Investigation and Soil StudiesGeotechnical engineering is the branch of civil engineering concerned with thebehavior of earth materials. Site investigations are needed to gain an understanding ofthe area in or on which the engineering will take place and in assessing risks posed by siteconditions. Geotechnical investigations include a site examination of soil, rock and seismicfaults in the area of interest to determine how they will impact proposed construction.American Land Title Association (ALTA)The American Land Title Association (ALTA) is a national trade association whose active members engagein the title industry and businesses relating to real estate, sales, construction and finance. ALTA and theAmerican Congress on Surveying and Mapping (ACSM) have jointly developed a general set of land surveyingstandards. The ALTA standards are a nationwide uniform set of standards and the survey often includesdetermining property lines, location of improvements, identifying all easements, utilities and other conditionsaffecting the property. An ATLA survey is commonly prepared for commercial properties to determine elementsto the property that insure the title to the land determining the ownership of the building that commercialdevelopment may require. The survey is specifically designed to satisfy the needs of lenders, corporations and titlecompanies when dealing with valuable commercial properties.Preconstruction Document and Cost ReviewsFor construction loans, AEI performs an independent review of construction documents (Architectural, Structural, Landscape,Mechanical, Electrical and Plumbing drawings and related specifications). The purpose of the review is to ascertain if thedocuments provide sufficient information for a contractor to prepare a thorough and accurate bid, and for construction toproceed with a minimum of cost-adding change orders resulting from missing information. As part of the process, AEI alsocompares the proposed cost schedule provided by the contractor/developer to costs that are derived from our owncalculations to determine if the proposed construction cost is higher, lower, or on target with the our cost projections. Projectcosts are reviewed to determine the adequacy of the projected budget. In addition, AEI reviews the projected constructionschedule provided by the contractor to see if it is realistic or aggressive and if there could be events such as routine inclementweather or possible labor actions that might affect the projected schedule.Construction MonitoringOnce the loan is closed and construction has commenced, AEI will review monthly contractor draw requests and walk theproperty to confirm that the work for which the contractor is requesting funds has been completed. The draw request mayinclude funds for both work actually in place and for stored materials, whether on site or in a remote location, for which bills oflading and insurance certificates are required. While the site visit is neither a safety nor code-compliance inspection, if anyquestionable methods or materials are observed, they will be reported for further inspection. Any deviations from the projectdrawings are also noted and reported. AEI also reviews all change orders to verify the validity of the charges.Construction monitoring is designed to compare the progress of construction work with the project schedule and is conductedthrough periodic visits to the construction site. More intensive monitoring may occur based on a client’s specific request. Thefinal phase of construction monitoring involves AEI providing the client with a report that includes findings and certification ofany costs or project milestones.
Site Investigation & Remediation AEI Consultants provides full service environmental site investigation and remediation services to address a variety of pollutant conditions to clients such as manufacturers, developers, commercial lenders, realtors, brokers and a wide range of banks throughout the United States. Site Investigation includes comprehensive examinations, appropriate design and plan installations and feasibility studies to determine the contamination severity and mitigation methods on contaminated sites. AEI’s dedicated engineers develop effective solutions in order to successfully completed thousands of site investigation and remediation projects on schedule. Our experienced project managers and professional geologists, engineers, and scientists identify cost-effective solutions and develop long-term relationships with our clients to understand their budgetary needs. AEI offers up-to-date knowledge of federal, state and local regulations throughout the United States. Quality control is strictly enforced. All work completed by AEI is thoroughly documented and performed under the direction of a Professional Engineer or a Professional Geologist. AEI is well-known in the industry for our superior quality of work and client satisfaction. Phase II Subsurface Investigations A Phase II subsurface investigation would generally be recommended if historical documents or a site inspection suggests that soil or groundwater contamination might exist at the subject property following a Phase I Environmental Site Assessment (ESA). The purpose of the Phase II Subsurface Investigation is to determine if contamination exist. Investigations determine the impact of the contamination on the soil and/or groundwater conditions beneath a property. Potentially contaminated sites that are recommended for Phase II subsurface investigations commonly involve: • Dry cleaning operations • Printing facilities • Manufacturing facilities • Gas stations • Underground storage tanks (USTs) • Leaking tanks • Hazardous materials surrounding the subject property All of AEI’s Phase II Subsurface Investigations are performed by experienced Professional Geologists who establish the scope of work, determine the location of each sample and interpret sample results. All samples are analyzed by certified laboratories under the guidelines established by the American Society of Testing and Materials (ASTM). Once the laboratory results have been acquired, a report is prepared which includes the subject property map, analytical laboratory sample results, and conclusions and recommendations for additional work, if required.
Site Investigation & Remediation Soil, Soil-Vapor, Indoor Air and Groundwater Investigations Soil, Groundwater and Soil-Vapor Investigations are performed to evaluate the extent of identified contamination to soil and/or groundwater beneath a property have been impacted. Site specific data is integral in evaluating the need for mitigation, human and environmental risks and obtaining regulatory closure. Extensive soil and water sampling and laboratory analyses may be necessary to determine the extent of the contamination and to appropriately characterize the subsurface geology, hydrogeology and distribution of multi-phase pollutants. In many cases installation of monitoring wells are needed for long term groundwater monitoring. AEI’s comprehensive testing and evaluation procedure gives our clients the necessary information to make thoughtful, prudent business decisions regarding site cleanup. Vapor Intrusion Studies Vapor intrusion and vapor encroachment is encountered primarily at sites contaminated with volatile organic chemicals such as petroleum from leaking underground storage tanks or pipelines and chlorinated solvents from dry-cleaning facilities. Vapor Intrusion studies may involve sampling indoor and ambient air, soil gases, and groundwater. State and federal environmental initiatives have recently addressed vapor intrusion issues and will have significant impacts on future real estate transactions. AEI’s experienced project managers have completed hundreds of vapor intrusion investigation studies at commercial and industrial properties. Monitoring Well Installation, Gauging and Sampling AEI performs groundwater quality investigations which involve installing groundwater monitoring wells in order to assess geologic conditions, groundwater flow, pollution fate and transport dynamics. AEI properly designs monitoring programs. Risk Assessments Risk assessments are a means of quantifying risks to human health and the environment. It is often used to develope site-specific clean up standards, thus allowing some contaminants to be left in place. Some of the factors that influence the outcome include: nature of property use (commercial or residential); contaminants of concern; depth to groundwater; and the proximity to sensitive receptors such as schools, water supply wells, and other water bodies. AEI utilizes the most current industry approach to conduct risk assessments to provide accurate interpretations of risk at a specific site. Remedial Investigations and Feasibility Studies Remedial Investigations and Feasibility Studies (RI/FS) both follow the preliminary site investigation and are conducted concurrently. The primary purpose of an RI is to determine the nature and the extent of the contamination and to establish whether it poses public health and environmental threats. The primary purpose of the FS is to assess the cost of the necessary treatment and to evaluate cost-effective alternative actions of remediation for the contaminants of concern. These studies allow our clients to make informed decisions and practical approaches regarding site cleanup.
Site Investigation & Remediation Remediation Design, Installation, Operations & Maintenance AEI offers the ability to evaluate a wide range of remedial options based on site specific data and regulatory considerations. With our turnkey remediation capabilities, AEI’s impressive track record in the design and implementation of remedial programs results in significantly reduced remediation costs for our customers. Our broad range of remediation capabilities includes regulatory support, remedial investigation, risk assessment, remediation engineering, field operation and management, and innovative technology. Our services include: • In-Situ and Ex-Situ Bioremediation • Soil Vapor Extraction / Bioventing • Chemical Oxidation • Product Recovery • Stabilization • Groundwater Extraction & Treatment • Engineering Controls (venting, vapor barriers, reactive barriers, etc) • Soil Excavation Corrective Action and Remediation Plans Design of a Corrective Action or Remedial Action Plan (RAP) for a site, incorporates all assessment data and prior experience in remedial investigations and feasibility tests. The RAP contains risk based cleanup levels negotiated with the regulator, and contains all of the information necessary to construct and operate the remediation system. The RAP also provides detailed procedures for monitoring the progress of cleanup and criteria for recommending closure. Upon approval of the RAP, the system is installed and operated until cleanup levels are met, or it can be demonstrated that the point of diminishing returns is reached. AEI is very cognizant of the need to maximize the value of client dollars spent on remediation. AEI’s track record includes numerous release sites that have gained case closure through the implementation of cost-effective remediation methods. Groundwater Monitoring and Treatment Typically required in the case of open release sites, AEI assists our clients with assessing the extent of groundwater contamination. Through the installation and sampling of a network of monitoring wells, the lateral and vertical extent of groundwater contamination and the rate at which the contamination is migrating toward sensitive receptors such as surface water bodies and water supply wells is evaluated. We assist clients in achieving the necessary documentation to proceed toward site closure, or risk assessment and remediation if needed.
Site Investigation & Remediation Site and Facility Closures AEI assists clients with achieving site closure or no further action (NFA) status with open release sites through monitoring, remediation, and regulatory reporting activities. AEI also assists clients with facility closure of industrial sites in the event that hazardous materials must be removed and facility equipment decommissioned. Proper closure is critical for lenders and property owners in connection with potential liabilities associated with former tenant operations. Redevelopment/ Brownfield Properties that become abandoned or underused due to suspected contamination are commonly referred to as “brownfields”. Brownfields often contain contaminants from prior operations. AEI works with commercial and industrial property owners and developers to identify potential legal responsibilities and integrate appropriate remedial measures for Brownfield sites. AEI provides a full range of services including due diligence (Phase I and Phase II assessments) and when needed pollution characterization and the evaluation and implementation of mitigation methods. Regulatory Assistance AEI’s comprehensive approach to delivering due diligence, site investigation and remediation, industrial hygiene and construction services assures clients they are managing their risks while meeting regulatory obligations in the most cost effective way possible. Occasions arise when additional regulatory assistance is needed. AEI’s national staff of experts can give compliance consultation and design plans for solving a host of issues regarding environmental regulations.
Industrial Hygiene Services AEI Consultants assists clients identify and evaluate potential risks associated with asbestos, lead, mold and radon. Asbestos and Lead Surveys AEIs qualified staff inspects and identifies suspect asbestos containing materials (ACMs) and characterizes sites for natural geologic deposits are known as "Naturally Occurring Asbestos" (NOA). Although the scope of an ACM or NOA survey may vary based on its purpose, they typically involve a visual inspection, sampling, analysis and a summary report, all conducted by trained and licensed inspectors. Depending on the clients specific needs, AEI can provide services from limited sampling for minor renovation projects to comprehensive surveys for demolition and major renovation projects, as well as dust mitigation plans during construction projects involving NOA. Facilities Surveys AEI provides a wide range of asbestos consulting and inspection services to public and private sector clients. AEI provides experienced registered EPA Accredited Asbestos-trained professionals on staff, experienced in providing clients with cost-effective solutions to asbestos concerns. AEI helps property owners meet legal requirements while reducing their liability exposure. Operations and Maintenance Plans Survey results are used to develop Operations and Maintenance (O&M) plans to assist property owners in managing asbestos-containing materials and/or lead paint that will remain in the subject building. Since total removal is not always desirable, feasible or affordable, O&M Plans allow for the safe and effective management of ACMs/LBPs. Asbestos Removal Project Design AEI provides in-house resources to develop detailed specifications for projects involving the removal of any or all ACMs. This includes project management, preparation of bid specifications and assistance in qualifying and selecting abatement contractors. Air Monitoring/Clearance & Project Oversight AEI provides air monitoring and project oversight to ensure that bid specifications are followed, safe work practices are utilized and air fiber levels are maintained below regulatory levels or project specific levels. Naturally Occurring Asbestos (NOA) Asbestos-containing dust can be generated when asbestos-containing rocks are crushed or broken through natural weathering processes or through activities such as construction, grading, quarrying or surface mining. This dust may pose serious health risks to people who inhale this material. There are important differences between ACMs and NOA. Primarily, the California Air Resources Board set a limit of 0.25% asbestos versus >1% asbestos for ACMs. Heightened data documentation is necessary in order to ensure correct characterization of regulated NOA. Most analytical laboratories are used to identify high grade mined asbestos, not NOA. AEI has technical staff experienced in every analytical aspect of asbestos including the ability to determine whether the NOA characterization fits with the EPA’s definition of regulated asbestos.
Industrial Hygiene Services Lead Surveys AEIs certified staff members are always up-to-date on the ever-changing lead regulations (including EPA’s Repair, Renovations, & Painting Rule) and how these regulations can potentially affect our clients. Lead-Based Paint Hazards AEIs certified and licensed staff can perform comprehensive lead based paint Inspections and Risk Assessments following HUD guidelines. AEIs staff members are experienced with X-Ray Fluorescence (XRF) sampling technology, as well as standard paint chip sampling and wipe sampling. Lead in Drinking Water AEI performs surveys to identify potential lead contaminant sources in water supplies for commercial and residential buildings. AEI assists in finding affordable and effective methods to reduce lead concentrations in drinking water to acceptable levels. Lead Operations & Management Plans Once the LBP hazard is quantified, AEI has the ability to aid owners and operators in developing cost-effective ways of managing the risks associated with LBP. AEI can create O&M plans to assist facility managers with a variety of interim controls to manage lead-based paint. Lead-Based Paint Abatement Monitoring In cases where the removal of LBP is necessary, AEI provides project management, bid specifications, construction inspections, waste manifest review and a project closure report following abatement. The EPA Repair, Renovations & Painting Rule now specifies that only contractors who are Lead-Safe Certified can perform renovations for projects involving the removal of more than 6 square feet of lead based paint in buildings constructed before 1978. AEI assists our clients during LBP removal projects to ensure that no lead hazards are present following abatement activities. Mold and Moisture Intrusion Surveys AEI’s staff conduct exposure assessments for airborne or surface mold and can identify suspect microorganisms and fungal spores. AEI can also determine structural deficiencies that may allow for moisture intrusion potentially leading to mold growth. No current standards for acceptable levels or tolerable quantities of bioaerosols (i.e., fungal spores and hyphal fragments) are given by the Center for Disease Control (CDC), the Environmental Protection Agency (EPA), the American Conference of Governmental Industrial Hygienists (ACGIH) or Occupational Safety and Health Administration (OSHA). However, in a report assessing the effect of molds on indoor air quality, the California Research Bureau concluded that, “all molds under proper conditions and concentrations are capable of adversely affecting human health. Therefore, it is clear that reduction and prevention of mold exposure is needed to decrease the risk of damage to human health.” The repair of water intrusion and the immediate remediation of visible growth are both critical to avoiding future health problems.
Industrial Hygiene Services Inspection and Remediation Protocols AEI employs only trained and experienced personnel to deal with any fungal problem. AEI is currently up-to-date with the ever-changing guidelines concerning mold inspection and remediation. Currently all of AEI’s mold investigations follow the ASTM E 2418-06 guidelines for assessing readily observable mold, as well as determining conditions and physical deficiencies conducive to mold. All recommendations derived from our inspections are in accordance with accepted guidelines determined by the EPA as well as the American Conference of Industrial Hygienists (ACGIH). Moisture Management Plans (MMPs) AEI can provide client-specific management plans that describe routines to manage moisture and prevent mold growth. These MMPs will also outline the steps to be taken if moisture and mold growth are discovered, specify who is responsible for remediation actions and provides adequate documentation to record all plan activity. AEI has successfully completed hundreds of mold surveys, remediation protocols and MMPs for a wide array of property management groups, real estate agencies and local government agencies. Radon Assessments Radon is a colorless and odorless radioactive gas that can be found in commercial buildings and homes across the United States. Nearly one out of every 15 homes in the US is estimated to have an elevated radon level (4 pCi/L or more). It originates from the natural breakdown of uranium in soil, rock, and water and infiltrates the air. According to the United States Environmental Protection Agency, radon is the second most frequent cause of lung cancer. In June 2003, the EPA revised its risk estimates for radon exposure in homes. EPA concluded that the effects of radon and cigarette smoking are synergistic, thus radon offers a higher risk of harmful effects than for non- smokers. EPA’s revised estimates are based on the National Academy of Sciences 1998 BEIR VI (Biological Effects of Ionizing Radiation) Report which concluded that radon is the second leading cause of lung cancer after smoking. AEI’s trained staff can conduct radon surveys according to the EPA radon-testing protocol, utilizing short-term “charcoal liquid scintillation” testing kits. We then issue letter reports explaining the testing findings. AEI provides radon testing and consulting services to public and private clients. Our trained professionals provide cost-effective solutions to radon concerns. AEI assists property owners and lenders to identify and reduce the environmental hazards associated with radon and if applicable, assists in finding licensed radon mitigation contractors as well as conduct follow-up testing.

Our experts have the ability to develop technical strategies in cooperation with the client and counsel, and perform background technical analyses for a particular site.
Industrial Hygiene Services Indoor Air Quality (IAQ) Investigations Indoor Air Quality (IAQ) investigations provide evaluations of air quality in public and commercial buildings. Indoor air quality is defined by the representation of concentrations of pollutants and thermal conditions that may negatively affect the health, comfort and performance of the subject building’s occupants. AEIs qualified staff inspects facilities to determine if IAQ parameter deficiencies are affecting the comfort and performance of the building’s occupants. The scope of an IAQ survey typically involves a visual inspection, occupant interviews and sampling of the subject building’s temperature, humidity, carbon dioxide, carbon monoxide and volatile organic compounds. AEI will also conduct an analysis of samples for mold, asbestos and lead and will provide a detailed report of our findings. Depending on the clients specific needs, AEI can provide services from limited complaint areas to comprehensive building IAQ surveys for sick building syndrome or building related illnesses. AEI’s parameter standards are taken from guidelines established by the EPA, the Occupational Safety and Health Administration (OSHA) and, when applicable, the American Conference of Governmental Industrial Hygienists (ACGIH) and the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE). The IAQ investigation report will summarize the conclusions of all the investigated parameters of the subject building. AEI will provide recommendations as to how to resolve any potential or existing IAQ problems.
